COMBINATION RADIATOR AND HUMIDIFIER Filed March 9, 1934 INVENTOR Harry 51' I/lfeZ'k b ATTRNEY Patented Nov. 6, 1934 coMBlNaTIoN-Ranraromm l HUMIDIEIEM 'rheobject ofA thisinvenuon iswpmvid a humidifier` and a radiatorin combination. l

These and other' objects ofy my invention Will beillustrated in the drawing, described in` the speciiication` and pointed out inthelclaimsl at the end thereof.`

In the drawing:

` Figure 1 is fa front elevationV of` the radiatorl Figure 5` is an enlargedvsectional view through' so one of" the spray nozzles used to apply Water to the humidifier.

Figure 6 shows a modifiedv form of the water supply pipe and the spray nozzles, in which the supply pipe and nozzles are locatedabove the hns and the water is delivered down onthe ns from In the drawing; like reference numerals indicate like parts. y i

In the drawing reference numeral 1 indicates a radiator for radiating heat, through which radiator` steam or hot water is` intended to cir-` culate. This radiator is'made up'of a series of upright sections, the two sections oneach end being of a standardtypesuch asaregenerally used in radiation, `while. theisix intermediatesections 2,72 etc. are of a special" type which will be ydescribed as follows;`

As shown in side elevation in Figure2`each` intermediate section 2 has two 4long'tubes 3` and 4 at the back, and atthe front each section has three short tubesat the top indicated'by the reference numeralsv 5,.6 and '1. The short tubes are connected to the long tubes` by2 the connections 8' at the bottom.

In each section asmall tube '9 is specially connectedto thelbottom ofthe short"tube6 and to theside orthe longtubeji; This gives the water or steam a special path cf circulation. On this tube 9 is a series of ns 10, 10, the tins being placed thereon at the rate ofseveral to the inch,

` the width of the fins being preferably two or three times the diameter of the tube. The object of the fins is to the more readily take the heat from the water or steam that circulates through the small tube 9 and radiate it therefrom.

i. tor on the line 2x-2a: ofFigure 1, vwith the front" Betweeneachl pa-ir ofthe-tubes 9F isplaced a sprayA nozzle; 12, which nozzle; is-` shown* ink en-` larged2 sectional' viewiin'Figure 5"; Eachlof-V these tubes are connected toiarhorizontahpipe-14forming aL part of the 'drip pan, wh'icl'if pipe inf't'urn" y connectsjto an upright` servicepipe 15", which 65 goesv through the floor, which pipe in=turni`sfco`nnected` to a4 service pipe" l'pwhich' is' connected to awater supply underpressure.`

The' spray nozzle 12 ,comprisesY an internally threaded sleeve'- 1'1 anda cap 18: Inside ofv this 701i cap 18-`is aplug*19*whichhasaj threaded collar 20 thereon; whichecollaris threaded? withfa male thread, which' thread engages withv a female thread' on the-inside oftheI cap: This provides for the `adjustment of the plug 19"' towards' and 755 aiway fronithe'opening 21 inthejcap ofthe spray nozzle'. 'Iheplug19is-'provided`vwith ai slot- 22` therein', ,which can be'engaged byal screw" driver' for' the purpose offturning `theplug-` to' adjust iti A sleeve-,23 islprovidedr having a maiethread on` the' upper endE thereof4 that also engages e with" tlieferriale4 threadon the inside ofthe cap. This sleevev hasa closed bottom; a's` indicated'at 424:; which bottom has a slot 25\irii`sli` which' a screw driverean be engaged for the purpose ofv screw- 815i;` ing the sleeve into place; This sleeve isl slotted with' vertical slots, as indicated' at 26, it beingunderstood thatlthe Water can owrup throughl the'pipe 13 and around the sleeve'23,' and between it and the outer sleeve 17, and between the-slots' 9015 26 into the sleeve, and then'on up past the plug 19, and past the mutilated'collar 20 The sleeve 23 isalso surrounded by a screen 27; wl'iichkeepsdirt from going through that might' otherwise clog' up the nozzle. The cap can be removed fromv 95: time to time `for the purpose of cleaning this screen. y

In operation, the-water Willbe sprayedithrough the opening 21Aonto a bale plate 30` which is placed above the spray nozzle, andV from there 100 drips down on the ns, from whichv it is evaporated bythe lh'ea't furnished thereto' through; the tube-9.A The heat furnished by the tubes ofthe radiator proper also helps to evaporate the water from the fins. The excess water drops into a drip pan 31, Where it is caught, and from which it drains by the tube 32.

i It will be noted that the drain tube 32 extends about half way up in the drip pan. This insures the maintenance of a certain water level in the 1`10 2 Y f o drip pan which adds to the humidifying effect if an excess of water is furnished.

For the purpose of regulating the supply of water to the spray nozzles, we provide a humdostat and a solenoid valve 45 having electrical connections 41, 42 to a transformer 43, it being understood that any of thevstan-dard types of solenoid vvalves and humidostats. and transformers may be used for this purpose. The solenoid valve closes when the humidity of the air in the room reaches the proper amount, and opens again when the humidity falls below that amount. In this way an ample supplyof water is furnished to the spray nozzles and insures the keeping of the air in the room yat the proper humidity.

is fastened to the -radiator by means of the bolts 51, 51 which engage with the radiator tubes'with suitabley washers and nuts, by which the plate isheldin placev` and which permits its easyremoval. The radiator behindthis plate forms an evaporating chamber inside of the radiator, which is concealed by the plate and is a part of the radiator, so that the radiator ismade to perform both the function of heating the room, together with the humidifying ofthe air in the room.

`A needle valve 55 is provided which limits the maximum amount of Vwater thatis furnished to the` spray nozzles. It will also beunderstood that in the pipes 15 and 32 unions 56 and 5'7 are provided whichcan be disconnected so that the drip pan and the spray nozzles and pipes associated therewith can-be removed bodily from the Aradiator. It willalso be understood that the drip pan restson a base 58 provided in the radiator.

In Figure 6 we haver shown a modied form of the nozzle, in which the pipe 60, which is the equivalent of thepipe 14, is placed near the top of the humidifying chamber and is provided with gooseneck nozzles 61, one for each tube 9, which deliver the water directly to the top iin 62 on the tubev 9, so that the water can drip .fromv one fin to another and be evaporated in so doing. The radiator section, the tubes 9, and the drip pan etc. will b e the same with this modification as has been described above.`
